The upper sides of the members I I areprovided with curved surfaces Hz: which are engaged by spring actuatedplungers I3, which plungers are mounted on the arm 2 which carries thespindle I and are yieldably thrustdownward by springs l4.

A short shaft I5 is rotatably mounted in the slide near the rear end atone end thereof and is provided with a downwardly extending arm I6,

Which is connected by a link I! with a corresponding downwardlyextending arm I8 attached to the the slide above the shaft I5, overhangsthe upperedge of-the rack 2i and holds it into engagement with the gearis. For reasons hereafter described the gear 26] is interchangeable withother gears of other diameters and for that purpose the guide block 23may be replaced with similar blocks of diiierent dimensions to properlyhold the chosen gear in mesh with the rack and the end of the rackattached to the bracket 22 is vertically adjustable so that it may beproperly alined with the gear in use.

Stop screws 24 are mounted on some part of the structure which does notslide horizontally such as the table 5 orpne of the tracks 8 in aposition to be engaged by the slide 2 to limit its sliding movement ineither direction and these screws may be adjusted so that the extent ofthe sliding movement may be varied or if desired for certain operationshereafter described both screws may be adjusted to' simultaneouslyengage opposite edges of the slide so that it will be held immovable.Stop screws Hm are also provided on a fixed portion of the slide 'I' andlocated to engage opposite sides of the lever I9 to limit itsoscillating movement in each direction.

Operation It will be seen that the mechanism described provides amachine in which thereis a spindle rotatable upon a vertical axis andhaving a cutter of the rosette cutter type and below which there is atable movable toward and away from the cutter in a direction parallelwith its axis. Upon the table the work holding clamp provides meansfor-holding a strip of molding which preferably has previously beenprovided with an upper curved surface and this'molding is held inposition to be engaged by the cutter when the table is moved upwardly. V

Assuming that the work hereafter termed molding and generally designatedas 25 is in place in the lowerclamp member 9 between the. guides 9a andthat the table 5 is in lowered position, then in this lowered positionthe upper clamping members rest lightly upon the upper surface of themolding and the molding maybe moved longitudinally in the clamp. In thislowered position it is to be understood that. the plungers I3 do notengage the upper surface Ila of the clamp members II.

The table may then be elevated by suitable meansprovided for thatpurpose and during the first part of such elevation the plungers I3engage the clamp members I I. and press them firmly against the moldingso that it is held tightly cutter 4. While the parts are held in thiselevated position with the cutter operating its full desired depth inthe molding and with the parts arranged as shown in Fig. 2 the lever I9is man ually oscillated which rocks the work clamp and molding thereinon the trunnions it by virtue of the arms I6 and I8 connected by thelinks I! and at the same time movesthe slide l on the tracks 8, thissliding movement being caused by action ofthe gear 20 travelling ontherack 2!. These movements produce what may be termed a rolling movementof the molding relative to the cutter 4.

A rocking movement of the molding relative to the cutter may beaccomplished by removing either or both the rack 2i and the gear 28 andby adjusting the stop screws 2% so that they will both engage oppositesides of the slides l to holdthe slide immovable in which caseoscillation of the lever !9 will merely cause rocking of the clamp andwork on the .trunnions ID trate the operation accomplished by therocking movement and the work accomplished there by, Fig. 4 shows: themolding 25 in a position where the cutter 4 is operating to cut a designwith the molding turned toits extreme position in one direction. Thecenter point If! indicates the axis of rocking which is co-incident withthe axes of the trunnions wand by moveinent of the lever ii) the moldingis caused to rock while the cutter icontinues to operate upon it causingthe cutter to follow the arc-shaped surface of the molding which are isconcentric with the axis Iii.

The rocking movement of the molding may be continued'throughout itsentire curved surface or maybe stopped wherever desired producing adesign elongated crosswise of the molding, said design having curvedends and elongated intermediary portions. The extent of movement of thework is limited by engagement of the lever I9 with the stop screwslfiawhich may be adjusted as desired. In the design shown a slightoverlapping of the figures occurs, that is, the cutter in producing onedesign overlaps longitudinally of the molding the next design whichproduces the effect shown. Greater or less spacing of the designslongitudinally of the molding would produce different effects performedby the same cutter. l g

Operation of the device to out a design by the so-calledrolling processand designs, so out are illustrated in Figs. 9, 10, 11, 12 and 13. Toproduce this operation and result the machine is arranged as showninFig. 2 with the gear 29 and rack 2I in place and the stop screws 2 5ad justed, to permit movement of the slide l. With the parts so arrangedand assuming that the work is in engagement withthe cutter and the leverI3 moved to one extreme position the molding will assume the positionshown in Fig. 9 and as the lever I9 is moved to its opposite positionthe moldingwill be caused to rotate about the axis I6 caused by movementof the arms i6 and i8 and the link I! and at the same time the axis i Swill be moved transversely of the molding causing the arc surface of themolding to assume a rolling motion relative to the cutter.

If it is desired by this rolling operation to'cut a circular design,orin other words, a design which would, if developed on a plain surfacebe circular, the cutter designated at to. in Figs. 9 and 10 should be ofsufficient diameter so that its cut- 'ti-n'g edge will be of-a lengthequal to the length oiithe arc of the design. With a gear of properdiameter to advance the axis t at'the same speed as rocking *o'f theperiphery of the molding, or in other words gear having a pitch diameterequal to the radius of the-curved surface of the molding,

. a truly circular design cut intothe curved surface may be produced as'shown in Fig. ll. However, by varying the diameters of :gear as relativemerits: both directions.

"tothe radius offthe'moi ing so that the axis it will beadvanced eith rslower or faster than the rocking or the 'peripheryof the molding,ellipses having their greatest diameters extending. either transverselyor -longitudina lly or" the molding .rnay be cut as illustrated in"Figs. 12 and 13'. In performing the'rolling-operation either the stopoperation may be beguninithe middle of the design and completed'bymoving the work both ways respectively therefrom as well as in any otherway.

It 'will also be u'nderstood that after completion of cutting a single:design the table 5 is lowered which automatically releases the up erclamp members Ma from the plungers' i i and'permits the molding to bemoved lengthwise to a proper position where repeated elevationoi thetable will out another design and this operation repeated throughout theentire length of the molding.

Themachine has been shown and described as withtl'ie spindle i mountedin the first arm 2 and the table 5 movable toward or away from thespindle and cutter 4. An identical result may be obtain'ed'in reversingthe movable parts wherein the table 5 with'the af'oredescribed' partsmount ed thereon is fixed and the rotating spindle! and knife 4 mountedto move toward or away from the work.

In the claims the termrosette cutter is to be defined as meaning thattype of cutter having its cutting edge extendingsubstantially.transversely of the axis of rotation of the cutter.

The invention has been herein shown and described in its preferred formin which the work is rocked or rocked and moved laterally on an axisextending substantially at right angles to the axis of a rosette cutterbut the invention is conceived in various modifications in which othertypes of cutters may be used and wherein Various results are obtained byrocking the work on axes located differently than perpendicularly to theaxis of the cutter and more particularly where the rocking movement ofthe work is accompanied by a lateral movement of the axis. The variousmodifications are not specifically shown nor described but the inventionas defined in the appended claims is to be considered compre-. hensiveof all forms of structure coming within their scope.
